High-Solids, High-Strength Urethane Top Coat

Are you looking for an extremely-durable, low-odor, protective topcoat that is amazingly simple to apply?

If so, UltraMax is the clear answer!

UltraMax is a clear, extremely-durable, high-solids, 100% aliphatic urethane that is frequently used as a top coat alternative to polishing procedures according to the UDT Grind and Seal system.

UDT’s Grind & Seal program is simple, cost-effective, and minimizes ongoing floor maintenance requirements. One primer-coat followed by a thin coat of UltraMax will provide extreme durability and protection without any buffing or frequent re-coating.

UltraMax is also commonly used as a protective topcoat for epoxy, chip and quartz broadcast systems!

With almost no odor, this 100% aliphatic urethane may be used in occupied spaces and it absolutely will not yellow from extended UV exposure. UltraMax will protect epoxy and concrete floors from harsh chemicals like Skydrol® and jet fuels along with heavy-industrial traffic loads from forklifts and other types of vehicle traffic.

UltraMax comes standard as a high-gloss but is also available in a semi-gloss sheen when it mixed with Ultra Grip abrasion and traction additive.
